(easy math question please help) find the value of x question #7

The sum of the interior angles in a triangle is 180 degrees. Therefore, if we add up all of these angles, they must be equal to 180.

64 + 85 + (4x + 27) = 180

176 + 4x = 180

4x = 4

x = 1

Let's check our answer!

4(1) + 27 = 31

31 + 85 + 64 = 180

180 = 180

Hope this helps!! :)

x=1

Step-by-step explanation:

The sum of the angles in a triangle is 180

64+ 85+ 4x+27 = 180

Combine like terms

4x+176=180

Subtract 176 from each side

4x+176-176 =180-176

4x = 4

Divide by 4

4x/4 = 4/4

x=1

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
